Super high pressure jet water cleaning

The surface treatment is becoming more and more common Cleaning with high pressure (up to 2500 bar) spray water can remove contaminants, corrosive substances and old coatings from the substrate surface The surface treatment method has two significant advantages: compared with conventional blast cleaning, high-pressure jet water will not produce dust that directly pollutes the environment, and can remove water-soluble salts It is very important to choose clean cleaning water, because unclean water may pollute the surface to be cleaned This cleaning method can produce a sufficiently clean substrate surface, but may not produce sufficient roughness on the steel surface The complete old coating on the substrate will be removed, but the original roughness of the steel under the coating will not change, but it should be noted that if the steel has been corroded, the rough corrosion surface should not be included in the roughness The disadvantage of high-pressure jet water cleaning is that moisture will be introduced into the surface of the substrate during the cleaning process, so flash rust will occur The degree of flash rust depends on the relative humidity of the substrate, the temperature of the substrate and atmosphere, and the cleanliness of the substrate surface.
